spb - i remember this well, 16 months was the lowest point, started dr jay but very loosely, did it for a 3 hr period at first, and waivered a bit, (i know he says don't waiver, but it was fine.
went camping at 18 months and must have woken the whole campsite up getting irate telling my ds -its finished! no more milk!!"
i started my explaining to him by saying that nighttime is for sleeping, and if you wake in the night mummy will have to say no boobies just cuddling. i kept on with this script.
it wasn't too bad, and when it was i gave in.
it did work for about 5-6 hours in the night, and then gradually gave up bf completely by 22 months.
he is 3 now and still insiste on putting his hand down my bra night and day but i'm about to get tough on that too as i'm 5 months pg and this is now driving me mental!
i stopped the day time feeds by prizing his mouth away from my nipple with a chocolate button!
good luck. i actually started feeling like a normal person about a fortnightr after stopping
